Meteors and You!

Meteors and You! was an astronomy book from the University of Sunnydale library's astronomy section.
The book contained elaborate, in-depth accounts of the history of—and myths about—meteors and different societies' understanding of them. Unknowingly it contained information on the Queller Demon in its myths which allowed the Scooby Gang to figure out what was going on with the Queller Demon attacking the residents of Sunnydale.
